It's a joke between the manga creators (Tanaka Strike is actually two women working together) they created Sakuya with the idea of a "male yandere" in mind and then in an interview said he was their favourite character because he was a yandere. In the manga they slip in little "yandere" moments for the hell of it, one little scene shows that he stalks Mahiru and even watches him sleep, plus gets jealous of other people who befriend Mahiru.
